Hello, guys!I'm a real newbie when it comes to whole Linux world. I've been using ubuntu 12.04 / 12.10 for a month or two and after some strange errors I started using Mint and I have been really satisfied with it.A week ago, I tried to update Linux Mint 14 using update manager app, as I do usually once a week, but this time an error showed up:E: apt: subprocess installed post-installation script returned error exit status 1This is what I got in terminal (when I clicked on "details" in error message window):

Since then, I've been searching internet for hours and hours but I haven't found a solution.I get the same error when I try to install or remove something.I tried to use command apt get -f install but it didn't work.Yesterday (and today, also) I tried to install Cinnamon, fsgamer (app that lets you minimize games in fullcreen), sublime text 2 and some other apps, nothing worked.Strange thing, I installed BleachBit two days ago with no problems.What should I do? I feel hopeless.

Download them separately (sorry but the file sharing site wont give me a link for all four at the same time). and copy them to /usr/share/keyrings. They are all public keys so there is no issue with privacy, and they are all encrypted anyway. (you need to use the slow download link).

See if that solves it for you.
